Too bad that Lastvin has become unavailable. Hopefully it's just a temporary technical anomaly, such as the domain renewal lagging, and not that the site is permanently down. It was a useful site and the most accurate of the VIN sites out there. The ability to save a data card as a PDF doc, as well as being able to provide a direct link to said data card, was a welcome thing.
This is why when I could, I always downloaded Lastvin data cards as a PDF and attached them to cars for sale listings here, rather than just providing a link to Lastvin.com as others have done. Having a hard copy is always preferable and welcome, and any attachment gets preserved here through system backups as opposed to links, which can (as we have seen here) expire temporarily or permanently.
